Brief introduction:
Alloy 690(N06690)'s a high Cr content nickel alloy with excellent resistance to many corrosive aqueous media and high-temperature atmospheres.
Its high Cr content gives it excellent resistance to aqueous corrosion by oxidizing acids(especially nitric acid) and salts, and to sulfidation at high-temperatures.
It also has high strength, good metallurgical stability and favorable fabrication characteristics.
